Torricelli's principle regarding fluid motion?
My principle, often called Torricelli's law, states that the speed at which a fluid exits an opening in a container is proportional to the square root of the height of the fluid above the opening. This concept emerges directly from considering how gravity acts upon the fluid. It is a direct application of the principles of motion and gravity to the behavior of liquids, illustrating that the force driving the outflow is directly related to the weight of the fluid column above.
